 - Fixed a bug where TypeScript deserialization would fail on Uppercase properties.[#4479](https://github.com/microsoft/kiota/issues/4479)
 - Changed URI template generation to reuse templates when required templates are absent across operations.
+- Fixed path deduplication logic to avoid double `Id` suffixes in indexer names in scenarios where the `Id` suffix is already present.[#4519](https://github.com/microsoft/kiota/issues/4519) 
 - Updated reserved name providers for Java and Php so that "object" can be escaped.
 - Fixes request builder disambiguation when child nodes had different prefixes for different paths with same parameters.[#4448](https://github.com/microsoft/kiota/issues/4448) 
 - Do not generate CS8603 warnings when enabling backing store in CSharp generation.
